Meraki has stated numerous times that they don't release any roadmaps and hardly any promiseware. I recall they have said this in the beginning of every quarterly update.
The things you listed sound like feature requests or shining a light to the roadmap type of things.
Like it or hate it but thats probably the reason you did not get a response. And will likely not get one here. At least from someone working in Cisco / Meraki.
And don't get me wrong. I would love to get them as much as the next guy..
